Box for receiving an electrostatic fabric

ABSTRACT

A box for receiving an electrostatic fabric includes a top cover, a sliding member and a bottom cover. The sliding member is received and slidable in the box, and has a fixing portion mounting with an electrostatic fabric and a tongue having a through opening adjacent to the fixing portion. Two resilient arms extend from the fixing portion toward the through opening of the tongue, and two sliding blocks are provided at free ends of the two resilient arms, in which the two sliding blocks cooperate with two stoppers of the top cover to selectively control the sliding member at a lock state and a release state. When the sliding member is located at a lock state, the electrostatic fabric extends outside the box through a first opening of the box, but when the sliding member is located at a release state, the electrostatic fabric retracts in the box.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a box for receiving an electrostatic fabric, which can avoid the electrostatic fabric being exposed to the environment to adsorb dusts when not to be used, thereby keeping its cleaning function.

2. The Prior Arts

As is widely known, it is very efficient to use an electrostatically charged fabric to clean surfaces of objects, such as optical disks, monitors, and optical components, due to the charges in the fabric attracting and holding dust particles. So, electrostatic fabrics are generally used in our everyday life. However, if the electrostatic fabrics are exposed to the environment when they are not used, they will easily adsorb dusts, thereby degrading their clean function. Hence, that is a big problem how to avoid the electrostatic fabrics being stained with dusts when they are not used. In addition, it is inconvenient to stow in order the conventional electrostatic fabrics.

Thus, it is desired to provide with a box for receiving an electrostatic fabric that allows the electrostatic fabric to extend outside the box when to be used and retract in the box when not to be used.

SUMMARY OF THE INVENTION

An objective of the present invention is to provide a box for receiving an electrostatic fabric, whereby the electrostatic fabric can be retracted in the box to avoid adsorbing dusts when not to be used, thereby keeping its cleaning function.

Another objective of the present invention is to provide a box for receiving an electrostatic fabric, which is convenient to carry and stow in order.

To achieve the above-mentioned objectives, a box for receiving an electrostatic fabric in accordance with the present invention comprises a top cover, a sliding member and a bottom cover. After the top cover and the bottom cover are assembled together, a first opening is formed at one end of the box and a second opening is formed at the other end of the box. The sliding member is received and slidable in the box, and has a fixing portion mounting with an electrostatic fabric and a tongue having a through opening adjacent to the fixing portion. Two resilient arms extend from the fixing portion toward the through opening of the tongue, and two sliding blocks are provided at free ends of the two resilient arms, in which the two sliding blocks cooperate with two stoppers of the top cover to selectively control the sliding member at a lock state and a release state. When the sliding member is located at a lock state, the electrostatic fabric extends outside the box through a first opening of the box, but when the sliding member is located at a release state, the electrostatic fabric retracts in the box. Hence, the electrostatic fabric will not adsorb dusts when not to be used, thereby keeping its cleaning function.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-3 and in particular to FIG. 3, a box for receiving an electrostatic fabric constructed in accordance with the present invention, generally designated with reference numeral 100, comprises a top cover 1, a bottom cover 2, and a sliding member 3. The sliding member 3 has a fixing portion 33 mounting with an electrostatic fabric 39 and a tongue 31 having a through opening 34 adjacent to the fixing portion 33. The bottom cover 2 has a first notch 22 and a second notch 24, and the top cover 1 has a third notch 12 and a fourth notch 14. The bottom cover 2 has but not limited to four positioning holes 21, and the top cover 1 has but not limited to four positioning pins 11 corresponding to the four positioning holes 21. When the top cover 1 and the bottom cover 2 are assembled together, the first notch 22 and the third notch 12 forms a first opening 52 (see FIG. 1) at one end of the box 100, and the second notch 24 and the fourth notch 14 forms a second opening 54 (see FIG. 4 b) at the other end thereof, so that the electrostatic fabric 39 can selectively extend outside the box 100 through the first opening 52, while the tongue 31 of the sliding member 3 selectively retracts in the box 100 through the second opening 54.

Also referring to FIG. 3, the top cover 1 has a hole 16, two guides 13 and two stoppers 15 respectively located at both sides of the hole 16, in which each stopper 15 has an inclined plane 151 and a vertical plane 152. The bottom cover 2 has a guiding post 23 corresponding to the hole 16 of the top cover 1.

The two sliders 35 extend from a top surface of the tongue 31, each of which is received and slidable in the two guides 13 of the top cover 1, respectively. Each slider 35 has an inclined plane 351 for easily sliding in the guide 13. Two resilient arms 37 extend from the fixing portion 33 toward the through opening 34 of the tongue 31, and top surfaces of the two resilient arms 37 at free ends thereof are located above the tongue 31. Two sliding blocks 38, each of which has an inclined plane 381 and a vertical plane 382 (see FIG. 4 a), are provided at free ends of the two resilient arms 37, respectively. Furthermore, Two hooks 36 extend outwardly from two opposite sides of the tongue 31 of the sliding member 3, respectively.

As described above, the two guides 13 on the top cover 1 act to guide the two sliders 35 of the sliding member 3 and keep the sliding member 3 from swaying in the transverse direction. Further, two ribs 18 projects from an inner surface of the top cover 1, and another two ribs 28 projects from an inner surface of the bottom cover 2. After the top cover 1 and the bottom cover 2 are assembled, the two ribs 18 abuts against a top surface of the fixing portion 33 of the sliding member 3, while the two ribs 28 abuts against a bottom surface of the fixing portion 33 of the sliding member 3, so as to maintain the sliding member 3 stable in the vertical direction.

In assembling, first, a helical spring 42 is sleeved on the guiding post 23 of the bottom cover 2; then, two springs 44 connects the two hooks 36 of the sliding member 3 and two fixing post 27 of the bottom cover 2; a button 46 having a flange 461, which has a larger diameter than a distance between the two resilient arms 37 and a diameter of the hole 16, is coupled to an end of the helical spring 42 and is biased by the helical spring 42 against the hole 16 of the top cover 1, and the flange 461 is between the hole 16 and the two resilient arms 37; the two sliders 35 of the sliding member 3 are received and slidable in the two guides 13 of the top cover 1; and finally, the four positioning pins 11 of the top cover 1 is coupled to the four positioning holes 21 of the bottom cover 2. Additionally, it should be noted that two of the four positioning holes 21 on the bottom cover 2 are formed on the two fixing posts 27, respectively.

Referring to FIG. 4 a, due to the restoring force of the two springs 44 (see FIG. 3), the tongue 31 of the sliding member 3 extends outside the box 100 through the second opening 54 of the box 100 and the electrostatic fabric 39 retracts in the box 100. Referring to FIG. 4 b, when pushing the tongue 31 of the sliding member 3 into the box 100, the inclined plane 381 of the sliding block 38 on the resilient arm 37 moves along the inclined plane 151 of the stopper 15 on the top cover 1 so that the vertical plane 152 of the stopper 15 and the vertical plane 382 of the sliding block 38 are in contact with each other to set them at a lock state. At this time, the electrostatic fabric 39 extends outside the box 100 through the first opening 52 while the tongue 31 of the sliding member 3 runs into the box 100. That means the electrostatic fabric 39 is at a use state. Also, the two springs 44 are in a tension state.

Referring to FIG. 4 c, when pushing the button 46 to lower the resilient arms 37 to release the lock state, the sliding member 3 is drawn back by the restoring force of the two springs 44 and thus the electrostatic fabric 39 runs into the box 100. That means the electrostatic fabric 39 is at a storage state. Hence, the electrostatic fabric 39 will not adsorb dusts when not used, thereby keeping its cleaning function.
